LAMP BURNER.

LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 323,173, dated July 28,1885.

Application filed January 12. 1885. (No model.)

To all whom it may concern# Be it known that I, RANDOLPH S. MAINS, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Lamp-l3urners, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention, relating to lamp-burners,has for its object to provide the burner with a draft and heat regulator which is interposed between the cone and the chimney, the said regulator being made a cone-shaped cap, and acting to concentrate the indraft of air into the flame, the draft and heat regulator also preventing the burner from becoming highly heated, thus rendering the lamp containing the burner non-explosive, and at the same time the exterior of the regulator acts as a light-reflector.

rIhe peculiar features in which my invention consists are pointed out in the claims at the end of this specication.

Figure l ofthe drawings shows, in vertical section, a burner embodying my invention7 the said ligure also showing part of a chimney and lamp-body. Fig. 2 is a side elevation of the burner partially broken out to show parts within it. Fig. 3 is a partial under side view of the burner; and Fig. lis a partial top view of the ring, having arms to constitute a holder.

The lamp-body A may be of any usual shape or material. The collar A', attached thereto in usual manner, is provided with Ventilating-holes 2, to permit the free ingress of air into the lamp-body to enable the oil to be subjected to atmospheric pressure, which insures better circulation of oil in the wick or wicks. Above the collar I have placed a ring, I), which is provided with three detachable arms, b', extended therefrom and adapted to support a shade, the said arms being screwed into the ring.

The screw-threaded base 3 of the burner is screwed, as shown in Fig. I, into the ring b, and to connect the ring of the holder with the collar of the lamp, so that the burner may be tipped over for filling, the ring b has been hinged to the collar bya hinge, b2, a catch, b, fast t0 the ring, engaging a pin or pr0jection, b4, of the collar.

The cone c, selected to illustrate my inven tion, is of ordinary shape; but I have shown it as having two wick-tubes, c ci, which .at their upper ends (see Fig. 2) are. curved to correspond substantially in shape with the dome or top of the cone, such construction insuring evenness of flame and convenience in trimming. The burner has usual chimneyholding arms or clamps, c3, and over these I have placed a globe-holder, d, composed of an annular plate, d, having a neck, d2, provided with an inturned flange, d3, the annular plate and the neck being provided, respectively, with openings 4 5, through which to supply air between the outside of the chimney and the inside of the globe, and to supply air at the bottom of the chimney to enter the burner and pass under and over the draft and heat regulator e, and also to aid in keeping the chimney cool. i

The draft and heat regulator e is made as a cone, which is interposed between the burner and the chimney, as shown in the drawings, and, as herein represented, the base orlowcr end, e', of the regulator is irregular in shape or waved, (see Fig. 2,) to enable air to pass between the base of the regulator and the surface upon which it rest-s, the said air rising between the interior of the regulator and the outside of the cone and being directed into the dame. The waved or irregular shape given to the base of the regulator also serves to support the base of the chimney thereon in such manner as to raise the base of the chimney above the base of the regulator,

so as to admit the passage of air between the base of the chimney and the outside of the regulator. The' air so admitted, besides supplying the flame with an additional amount of atmospheric air to support combustion, also acts to cool the chimney and cone, preventing overheating the latter, thus avoiding explosion.

In practice the regulator will preferably be made of nickel-plated metal, to enable the outside of the regulator to act as a reflector.

In case, for any reason, .it should be desired to remove the globe-holder, the base of the regulator e may be set directly upon the burner, and, as herein shown, it might be set upon the outer flange, 10, of the base of the burner.

The lower end of the burner has attached to it a metalloop, m, shaped to leave a space suf- IOO ciently wide to receive a feeding-wick, the width of the loop being sufficient to keep the legs of the feeding-wick pressed against the two wicks n n2, as will appear in dotted lines, Fig. 1.

I have herein shown a shade-holder provided with arms, the ring of the shade-holder being hinged to the collar of the lamp; but I desire it to be understood that the said shadeholder is not herein broadly claimed, as it forms the Subj ect-matter of another application made by me, Serial No. 152,581, filed January 12, 1885.

I claim- 1. The specific means for holding a chimney, globe, and shade upon a lamp to insure a proper draft and permit the uncovering of the fount without removing the chimney, globe, or shade, consisting of a burner having chimney-clamps c3, a globe-holder, d, comprising the perforated annular plate d', perforated neck d2, and iiange cl3, a ring, b, having shadeholding arms b', and the lamp-fount collar A, to which said ring is hinged, substantially as shown and described.

2. The burner having two wick-tubes to receive two Wicks, n n, and provided wit-h a loop, m, to receive a feeding-wick, the said loop keeping both legs of the feeding-wick in Contact with the main wicks nnl, substantially as described.

3. The burner, its cone c, and chimneyclamps c3, combined with the heat and draft regulator e, having the horizontal waved base e, as shown and described, interposed between the cone and chimney, as set forth.

4. The combination, with the burner audits clamps c?, ofthe globe-holder, shaped as shown and described, and provided with openings 4 and 5, for the passage of air, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

RANDOLPH S. MAINS.
